EDS spectra and the analytical results. (a and b) EDS spectra at the top and middle positions of a CdS nanoneedle grown at the 475°C
substrate temperature (in VLS mode); (c and d) the analytical results of the above EDS spectra. Panels (a) and (c) show the EDS spectrum and its analytical result of the half ball on the top of the
CdS nanoneedle (shown in Figure 5b), respectively; panels (b) and (d) show the EDS spectrum and its analytical result of its main body.
